The mapping is based of secondary data sources for bottom fishing pressure (OSPAR), sediment type and organic carbon (OC) content (Smeaton et al 2021), and sediment lability as a function of grain size (Smeaton et al 2022). A new calculation methodology has been created to estimate the potential vulnerability of OC to bottom fishing induced disturbance as a function of sediment grain size and resettling speed. This allows for the potential OC lost through lateral transportation, consumption, or remineralisation as a result of bottom fishing disturbance to be estimated. By using fuzzy set theory, the potential vulnerability of sedimentary OC is estimated and mapped for the UK EEZ. All calculations and modelling were carried out within the ESRI ArcGIS software package using the spatial overlay, raster calculator and the zonal statistics tools. Full details of the study and methodology can be found in Black et al. (2022) and relevant supporting documents.
